Application filed. November 29, 1918. Serial No. 264,595.

To all whom it may concern Beit known that I, RUDOLPH Or'ro TRUEB, a citizen of the United States, and a resident of Murray Hill Park, county of Union, and State of New Jersey, haveinvented certain new and useful Improvements in Frames for Manufacture of Embroidery, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, wherein- Figure 1 is a perspective view, and

Fig. 2 a sectional view on line 2+2, indicated in Figxl, of an embroidery frame, constructed according to my invention; 7

Fig. 3 is a detail, a plan view, drawn on an enlarged scale, of a portion of one of the transversebars of the frame; I

Fig. 4 is a sectional view thereof on line l4, indicated in Fig. 3; 7

Figs. 5, 6 and 7 are perspective views of the device for laterally stretching the fabric; Fig. 5 showing the hook and buckle, and Figs. 6 and 7 the part attachable to the edge of the fabric;

Fig. 8 is a plan view, and Fig. 9 a sectional view on line 99, indicatedin Fig. '8, of a modified construction of the part in the form of a clamp.

My invention relates to appliances for manufacture of embroidery, and consists in devising the construction of a frame, and of the appliances used in connection therewith for stretching the fabric, whereon th embroidery or other ornamentation is to be produced.

The frames, heretofore known and used for this purpose, were composed of four bars, provided with means for adjusting them in requisite positions to each other, and with means for attaching the fabric to the bars by basting. In using these frames the edges of the piece of fabric are basted to'the strips of cloth, secured to the bars of the frame, and then stretched by shifting the bars apart.

This procedure consumes a great deal of time and yet the result is not at all satisfactory, the means for fixing the bars in position relatively to each other being usually holes made in the bars at certain intervals and pins or bolts. The stretching of the fabric, basted to the strips on the bars, being feasible only by moving the bars apart, it frequently happens, that the distances between the holes in the. bars are too far apart, or too near together, to so effect the requisite stretching of the piece, on which the embroidery is tobe produced, and

then it becomes necessary to baste on, onto the strips, or onto the fabric, additional strips of material to enable the adjustment of the frame to be made for the requisite stretching of the fabric. This, of course, consumes additional time, and yet the ultimate result is no more satisfactory because it is seldom feasible to obtain the right degree of stretching the fabric by the means provided for the adjusting of the bars of the'frame at the right distance from each other. in both directions. To remedy these defects 1 have devised the frame, and the appliances to be used in connection there with, asthey are illustrated in the drawings and hereinafter described. 7

.Referring to 1 of the drawing aand a are the main bars of the frame; 6 and b are the side bars. The main bars a and o are slotted on their ends and the side bars I) and b are inserted in the slots 0.

The nds of the barsand b are fixed to the ends of the bar a by bolts d, or may be secured thereto otherwise, it being necessary, in the using of my improved frame,

that only the bar a be moved nearer to, or

farther away from, the bar a. In the other ends of each of the bars I) and Z) a series of holes eis made and pins f (or bolts) are provided for fixing the bar a at the requisite distance from the bar a to enable the piece of fabric, whereon the embroidery is tobe produced to be stretched between them.

For the fasteningof the fabric to the bars a and a the metallic strips 9 (see Fig. 3)

secured thereto bynails h, or other fasteningmeans, are used. On these strips 9 the prongs g are formed, and a groove z is formed in the bars a and a as shown in Fig. 4, into which the prongs g are bent. Strips of flexible material is are secured to the bars a and a by nails Z, or other suitable means to serve as a protecting cover, or guard, to prevent the hands of the operator from coming in contact with the prongs.

For lateral stretching the part of the fabric,'whereon the embroidering is to be pro duced, I combine with the frame, in the way shown in Fig. 1, two or more of the devices, illustrated in enlarged detail in Figs. 5 to Each of these devices comprises the metallic hook on fitted upon the side bars 6 and Z) the buckle a secured thereto, the pronged bar 0, the cover 0 therefor prefer ably hinged thereto as shown, or inlieu thereof a clamp, constructed asillustrated in Figs. 8 and 9, and the strap 39, having one end secured to the pronged bar 0, or

to the rear ends of the jaws g of the clamp,

and its other end drawn through the buckle n, and held by the prongs a when the fabric is laterally stretched.

The hook m is made preferably of a fiat strip of metal bent'to fit the side bars I) and b, and the buckle n is fastened to its end by bending the end of the metallic strip over the middle bar of the buckle. A rivet m (see Fig. 5) may be used to better secure the buckle n to the hook m; it is however, not considered essential to do so, practical experience having shown that the bending over of the metallic strip, over the bar of the buckle a is sufiicient. The free end of the strap p is passed through the buckle n from above and the prongs a are curved downwardly to permit the "strap 79 to slide thereover when drawn taut. Also the prongs 0 of the bars 0 are slightly curved inwardly or toward the face of the bar '0, though their points terminate some distance above it. The cover 0 is preferably hinged to the bar 0 if niade also of metal, but may also be made of such flexible material as the covers 70 on the bars a and a, andfastened along therear edge of the bar o'bin'any suitable wa c S o'me' pieces of fabrics do not have edgings suitable to be attached to prongs as provided on the bar 0. For such materials it is more suitable to use the clamps illustrated inFigs. 8 and 9. These clamps are composed of the two jaws g and g hinged on the pintle rand arms 8 and is. having their ends slotted at t to enable the strap 1?, to be drawn through and looped as shown in Fig. 9. Along the front-edges of the jaws q and 9 strips 'u'of rubber, or of'other compressible material, are secured, forming lips, between which the fabric is gripped and held when the strip 1) is drawn taut, whereby the rear ends 8 and s of the j aws are drawn together, this action being translated in pressing the front edges of the jawstogether.

To stretch a piece of fabric upon the frame, constructed according to my invention, it is best to proceed as follows: The bar a"is"set at a distance from thebar a to make the space between them slightly wider than the strip of the fabric to be'embroidered. If the embroidering is to be done ona part of a piece of fabric of greater the part of the fabric above the margin of the part, on which the embroidering is'to be produced, is wound upon the bar'a (or a/ as the case may be). In doing this the fabric is gently stretched longitudinally and held even laterally. Next the longitudinal edges of the part of the fabric,"be'tween the bars a and a", are attached to the prongs 0 of the bars 0 or clamped between'the jaws of the clamps, the straps p passed through the buckles a, and attached to'the prongs n. Then thestretching of the fabric is completed "byadjusting the straps to eifect an even stretching of the fabric between" the bars of the frame. Those "who are familiar with the art understand that'some fabrics require a harder stretching than others, and they will appreciate the great facility, which my improvement affords for rapidly and easily effecting every degree'of' stretch-.

, They will also appreciate the saving of time in preparing and setting the fabric intojthe frame and preserving of the material from injury, and distortion, which the improvement affords.

I claim as my invention:

A frame for stretching fabricscom'prisingj two main bars andtwo side -ba'rs,"the main bars being provided each. with arow of prongs for securing the fabric thereto, and one of the main bars being adjustably connected to the ends of the two sidebars; short sections of bars also provided each with a row of prongs for securii'i'g the' fabric thereto, hooks fitted to the side bars, buckles connected to the hooks,-'and-straps connecting the short sections of bars with the buckles; substantially as herein shown and described.
